Title: Synchronization method for digital radio communication
Inventor: MIYATSU KAZUHIRO
IPC: H04B7/26
Filed: 1993-06-30
Abstract: PURPOSE:To extend a communication enable range under the circumstance of fading by including a signal acting like a pilot signal to a predetermined position in a synchronizing signal or a preamble inserted by a transmission system for the synchronization of a reception side in digital radio communication. CONSTITUTION:A transmission system forms a transmission signal by selecting a position of a signal acting like a pilot signal in a preamble of the transmission signal. A fading correction circuit 23 and an amplitude limit circuit 24 are newly added to a pre-stage of a matched filter 21 in a synchronization circuit 2 of a reception system. The fading correction circuit 23 extracts a signal for a time slot equivalent to number (9 from p1 to p9) of the preambles from the head of the reception signal and regards signals (p1, p3, p5, p7, p9) located to the time slot for a predetermined time as the pilot signal to execute processing for fading correction.

Inventor: TANAKA HIROSHI
IPC: B21D7/06
Filed: 1983-10-12
Abstract: PURPOSE:To prevent generation of a flaw, and to raise its quality and its productivity by pressing a work set in a horizontally placed attitude, in the horizontal width direction and executing edge-push working, by a cam mechanism sliding in the horizontal direction by descent of a ram of a press machine. CONSTITUTION:When a work W is fitted into a fixed groove, and a ram R is lowered, an auxiliary plate 27 contacts a reference plate, and the work W is held between a slide cam 15 and a base board 11. When the ram R further descends, a front inclined surface 25a of a rolling reduction device cam 25 pushes out a drive cam 10 in the forward direction, while sliding down along a rear inclined surface 10b. By keeping pace therewith, an auxiliary plate 24 also pushes down the slide cam 15 and the base board 11, a rear inclined surface 15b slides down along a front inclined surface 10a of the cam 10, and the cam 15 goes ahead and advances to the maximum position. As for the work W, one side is held by the fixed groove, therefore, it is pushed forward to an edge-push working die 14 and curved, but since the front face of the other end is controlled by the reference plate, the curved part is brought to necessary edge-push working along the front face of the working die 14.

Title: Magnetic recording medium
Inventor: MIYATA TERUHISA
IPC: C09D167/00
Filed: 1986-08-13
Abstract: PURPOSE:To improve the surface smoothness of a magnetic layer and to decrease the surface electric resistance thereof by providing an intermediate layer contg. a binder contg. the polymn. cured resin of a (meth)acryloyl compd. incorporated with a (meth)acryloyl group in the hydroxyl group position of dipentaerythritol and conductive fine powder between a nonmagnetic base and magnetic layer. CONSTITUTION:The (meth)acryloyl group incorporated in the hydroxyl group position of the dipentaerythritol exists in the (meth)acryloyl compd.; therefore, said compd. is compounded together with the conductive fine powder into a coating compd. for the intermediate layer and such coating compd. is coated on the nonmagnetic base and is dried. The coating can be easily polymn.-cured by projecting radiation thereto after a calendering treatment. The formed intermediate layer has the extremely high effect of the calendering treatment as the glass transition point of the (meth)acryloyl compd. is low. The surface smoothness as extremely good as <=0.010mum surface roughness is thereby imparted to the magnetic layer although the conductive fine powder is incorporated into said layer.
